Claims

[Scope of utility model registration request]

A magnetic tape cassette including a cassette case consisting of an upper case and a lower case, a front cover having end plates pivotally attached to both ends of the front part, and a front cover locking mechanism, wherein the locking mechanism is configured to lock the cassette case at both ends of the case. A lock lever provided on one of the lock levers and operated by a lock release means on the recorder side, a compression spring that always biases this lock lever toward the end plate, and a lock lever that can be engaged with a locking pawl of the lock lever. and a locking portion provided on one end plate of the front lid, and the lock lever has a portion that is inserted into a guide recess provided in one case and guided by the guide means of the one case. 1. A locking mechanism for a magnetic tape cassette, comprising a sliding member, the sliding member further having a portion guided by a position regulating rib provided on the other case.
